The Bosch Rexroth Z2DB10VD2-4X/200V (R900411358) is a high-performance industrial hydraulic valve designed for reliable pressure relief at set pressures. This mechanically actuated valve boasts a variable spindle with an external hexagon, ensuring precise control and ease of adjustment. It is a pilot-operated spool symbol A B, B A valve that can handle a maximum pressure as specified by its product group ID.
Equipped with multiple ports, the Z2DB10VD2-4X/200V valve offers flexibility in hydraulic system design and integration. Its mechanical actuation ensures robust performance in various applications, while its size and max flow capacity accommodate substantial hydraulic throughput. The connection type is an interim assembly with a connection diagram compliant with NFPA T.. R D Size CETOP D and ISO standards.
The number of switching positions and the weight of the valve are optimized for its function. It utilizes FKM seals and is compatible with a range of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR to suit different operational requirements.
The Z2DB10VD2-4X/200V features one or two pressure valve cartridges within its housing structure. The system pressure can be finely adjusted to meet specific needs via various adjustment types such as rotary knobs or sleeves with hexagons.
This Bosch Rexroth valve operates by closing initially until the pressure in channel A surpasses the spring-set value; then it opens to regulate the system pressure effectively. Its design includes corrosion protection for longevity in challenging environments.
With options for one or two cartridges and several adjustment types for precise pressure customization—including rotary knobs (standard or lockable) and sleeves—the Z2DB10VD2-4X/200V offers versatility for engineers looking to maintain optimal hydraulic system performance.

Pressure valves of type ZDB and Z2DB are pilot-operated pressure relief valves in sandwich plate design. They are used for limiting a system pressure. The valves basically consist of the housing (7) and one or two pressure valve cartridges. The system pressure can be set via the adjustment type (4).
In the initial position the valves are closed. The pressure in channel A acts on the spool (1). At the same time, pressure is applied to the spring-loaded side of the spool (1) via nozzle (2) and to the pilot poppet (6) via nozzle (3).
If the pressure in channel A exceeds the value set at the spring (5), the pilot poppet (6) opens. Hydraulic fluid flows from the spring-loaded side of the spool (1), nozzle (3) and channel (8) into channel T (TA). The resulting pressure drop moves the spool (1) and opens the connection from A to T (TA). In channel A, the pressure set at the spring (5) settles.
